MEEN40020 Mechanics of Fluids II

Academic Year 2023/2024

This is an intermediate course in fluid mechanics mainly for mechanical engineers. The module will take place during Autumn and will consist of 36 lectures (3/wk), 2 laboratory exercises, 1 class test and 1 end of trimester examination.
EXTERNAL FLOW: Streamlined and blunt bodies; Lift and drag; Friction and pressure drag; Reynolds number in external flow; Viscous dominated flows; Creeping flow; Inertial dominated flows; The boundary layer; Laminar and turbulent boundary layer analysis; Friction and drag coefficient; Impact of curvature; Separation; Aerodynamic lift; Stall; Case studies on circular cylinder and symmetric aerofoil
COMPRESSIBLE FLOW: Compressibility; Thermo-fluid relations; One-dimensional flow; Speed of sound;Mach number; Isentropic flow; Non-isentropic flow; Normal shock waves; Oblique shock waves; Fanno flow; Rayleigh flow; Quasi-one-dimensional flow; De laval nozzle
TURBOMACHINERY: The Euler equation; Radial flow machines: (Coriolis effect, slip, rotating stall, thermodynamics of radial-flow machines, choking, surge, performance characteristics); Axial-flow machines: (reaction ratio, sources of loss, polytropic and isentropic efficiencies, thermodynamics of axial-flow machines, factors limiting the performance of axial-flow compressors, performance characteristics).
